Description

  The present invention relates to the technical field of mobile terminals such as mobile phones. In particular, the present invention relates to a technical field of a portable terminal that notifies a user of a state such as an incoming call by voice output and vibration.

  2. Description of the Related Art Conventionally, a cellular phone that is a typical portable terminal can generally output sound (sound) from a speaker and vibration output of a vibrator when a state such as an incoming phone call or an incoming mail occurs. The user can set one or both of the output modes as the operation mode of the mobile phone according to his / her preference.

  That is, when a general user sets the ringtone level (volume, volume) of such a mobile phone, it is annoying for himself or others in the situation where the user is in a relatively quiet room. It is often set to a level that does not become necessary. On the other hand, when carrying a mobile phone, a user often carries a cellular phone in a clothes pocket for men and in a handbag for women. For this reason, even if a ringing tone is generated in these states, the incoming call may not be noticed depending on the fighting situation in the surrounding environment where the user is located (a busy place such as a downtown area or a station).

  Therefore, in general, a user avoids such a situation by selecting an operation mode in which a notification by vibration is performed in addition to the ringing sound when a mobile phone is received. If such an operation mode is set, the user can recognize an incoming call by a notification by vibration, for example, through clothes or a handbag, even in a noisy surrounding environment.

  Here, as a prior art existing prior to the present application, for example, there are the following patent documents.

  That is, Patent Literature 1 proposes a remote control terminal (remote control terminal) that automatically adjusts the speaker output sound of a television that is a remote operation target. In this document, the remote control terminal includes a microphone, and the speaker output sound of the television is collected by this microphone. Then, the remote control terminal remotely adjusts the volume setting of the television so that the difference between the collected volume and the reference volume preset by the user is maintained within a predetermined range.

  Patent Document 2 proposes a mobile phone that automatically adjusts the sounding mode of a vibrator. In this document, the mobile phone collects the sound pressure level at the time of vibration of the vibrator and the sound pressure level at the time of stopping with the microphone of its own device, and the difference between the sound pressure levels is a preset threshold. If it is larger than the value, the vibration of the vibrator is stopped or weakened.

Japanese Patent Laying-Open No. 2003-304590 (paragraph numbers 18, 19, FIGS. 1, 8) JP 2004-056623 A (paragraph numbers 19 to 24, FIGS. 1 and 2)

  By the way, consider the use situation of a user who has a mobile phone set in an operation mode in which the above-described audio output and vibration output are used together. In this case, after the user moves into a room in a quiet environment, it is often the case that the mobile phone with such settings is taken out of clothes, a handbag, etc. and placed on furniture such as a table with a hard surface. Moreover, a general user often forgets the operation settings of the mobile phone that he / she has performed.

  In this situation, when the mobile phone receives an incoming call, the ringtone output and the vibrator drive overlap, so that the mobile phone vibrates on the furniture surface. This will cause a humming sound. For this reason, the user is surprised by the generation of an unpleasant sound that accompanies the sudden start of vibration output, and there is a problem that it is difficult to hear the output ringtone (such as the sound becoming muddy).

  In recent years, the ringtone of a mobile phone is not limited to the conventional function that the user simply recognizes the incoming state as represented by services such as so-called ringtones and ringtones, but also the ringtone itself of the melody. New usage forms that users enjoy are widespread. For this reason, when an unpleasant sound resulting from vibration output occurs in the above-described operation setting and user's usage environment, a situation occurs in which it is difficult for the user to hear a ring tone such as a melody set with great effort (such as a sound becoming muddy). . Leaving such a situation may affect merchandise and customer satisfaction for mobile phone manufacturers and the like.

  Further, in this case, there is a possibility that the mobile phone may malfunction due to dropping from the furniture surface due to vibration.

  Accordingly, the present invention provides an operation mode of vibration output in accordance with the surrounding situation in an operation mode in which audio output from a speaker and vibration output by a vibrator are used in combination when a predetermined state occurs (for example, when an incoming call occurs). It is an object of the present invention to provide a mobile terminal, a state notification method thereof, and a computer program for the mobile terminal that allow the user to recognize the occurrence of the predetermined state reliably and comfortably by appropriately adjusting.

  In order to achieve the above object, a portable terminal according to the present invention has the following configuration.

In response to occurrence of the predetermined state, sound output from the speaker and vibration output by the vibrator are executed, and sound collection by the microphone is executed for the state in which the sound and vibration output are being executed. Two control means;
When the difference between the sound collection result (D2) by the second control means and the sound collection result (D1) by the first control means is larger than a predetermined threshold value (D), the vibration output by the vibrator is Vibration output limiting means for limiting the output mode (stopping, damping, etc.);
It is characterized by providing.

In a preferred embodiment, further comprising third control means for performing sound collection by the microphone in a state where neither the sound output from the speaker nor the vibration output by the vibrator is executed.
The vibration output limiting means is
The predetermined threshold value may be determined based on a sound collection result (D0) by the second control means.

Further, for example, the vibration output limiting means is
While limiting the output mode of the vibration output by the vibrator, the output mode of the audio output from the speaker may be enhanced.

  This object is also achieved by the state notification method corresponding to the mobile terminals having the above-described configurations.

  The object is also achieved by a portable terminal having each of the above-described configurations, and a computer program for realizing the corresponding status notification method by a computer, and a computer-readable storage medium storing the computer program. Achieved.

  According to the present invention described above, in the operation mode in which the sound output from the speaker and the vibration output by the vibrator are used together when a predetermined state occurs, the operation mode of the vibration output can be accurately adjusted according to the surrounding situation. Accordingly, it is possible to provide a portable terminal that allows the user to recognize the occurrence of the predetermined state reliably and in good mood, a state notification method thereof, and a computer program for the portable terminal.

That is, the present invention is premised on a portable terminal that is provided with a microphone and that can simultaneously use a sound output from a speaker and a vibration output by a vibrator when a predetermined state occurs. And in the present invention,
The sound output from the speaker is executed in response to the occurrence of the predetermined state, and the first sound collection result (D1) is obtained by collecting the sound output execution state with the microphone. Acquired,
In response to the occurrence of the predetermined state, the sound output from the speaker and the vibration output by the vibrator are executed, and the sound and the vibration output being executed are collected by the microphone. Obtain the second sound collection result (D2),
When the difference between the second sound collection result (D2) and the first sound collection result (D1) is greater than a predetermined threshold value (D), the output mode of the vibration output by the vibrator is limited. .

  According to the present invention having the above-described configuration, the operation mode of vibration output can be accurately adjusted according to the surrounding situation detected through the microphone. Therefore, for example, it is possible to minimize the generation of unpleasant sound caused by vibration of the mobile terminal on the furniture surface due to the vibration output of the mobile terminal. It can be recognized well.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention applied to a mobile phone which is a representative mobile terminal will be described in detail with reference to the drawings.

[First embodiment]
FIG. 1 is a block diagram illustrating the configuration of a mobile phone to which the present invention can be applied. In the figure, the cellular phone 1 roughly includes an antenna 52, a transmission / reception circuit 53, a display device 54, an input device 55, a control circuit 56, a vibrator 57, a speaker 58, a microphone 59, and a nonvolatile memory 60.

  That is, the transmission / reception circuit 53 performs processes necessary for transmission / reception of radio signals such as modulation and demodulation in accordance with instructions from the control circuit 56. At that time, the antenna 52 transmits or receives a radio signal.

  The input device 55 is a numeric keypad, a function key, a pointing device, and the like, and is used by a user to perform various settings and selection operations. The microphone 59 collects voice or the like uttered by the user and inputs a voice signal corresponding to the collected voice to the control circuit 1.

  The speaker 58 outputs the other party's voice or ringtone (melody etc.) during a telephone conversation in accordance with an instruction from the control circuit 56. In the present embodiment, the ring tone includes not only various melody preset in the mobile phone 1, but also so-called ringtones and ringing songs, and synthesized sounds such as singing voices that the user has acquired from the outside according to his / her preference. . Vibrator 57 notifies the user of an incoming call state or the like by vibrating in accordance with an instruction from control circuit 56.

  The non-volatile memory 60 stores a software program (hereinafter sometimes abbreviated as “program”) for controlling the operation of the mobile phone 1, user data (e-mail message, address book, incoming melody, etc.) and the like.

  The display device 54 includes a liquid crystal display panel or the like, and displays various screens according to instructions from the control circuit 56.

  The control circuit 1 performs overall control of the operations of the above components of the mobile phone 1. The control circuit 1 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, and hardware (not shown). The control circuit 1 controls the operation of each unit of the mobile phone 1 described above by executing the program group read from the nonvolatile memory 60 while using the RAM 103 as a work area.

  It should be noted that general techniques can now be employed for operations such as data transmission / reception processing and voice call processing performed by the mobile phone 1 with an external device in the above-described device configuration. For this reason, the detailed description in this embodiment is abbreviate | omitted.

  Next, an aspect of the incoming call notification operation that is characteristic of the mobile phone 1 according to the present embodiment will be described.

  FIG. 2 is a flowchart showing an incoming call notification process performed by the mobile phone in the first embodiment. This flowchart represents a processing procedure of a software program executed by the CPU 101 in order to notify the user of an incoming call to the mobile phone 1 in this embodiment.

  That is, in FIG. 2, the CPU 101 decodes the received radio wave by the transmission / reception circuit 53 and determines whether there is an incoming call such as a telephone call or an e-mail (step S101). When CPU 101 detects an incoming call in step S101, CPU 101 outputs a ringtone from speaker 58 (step S102). Further, the CPU 101 collects (detects) the ringtone output from the speaker 58 with the microphone 59 and measures the sound pressure D1 of the collected ringtone (step S103).

  Next, the CPU 101 further outputs a vibration by driving an actuator (not shown) of the vibrator 57 while continuing to output the ring tone from the speaker 58 (step S104). Then, the CPU 101 collects the ring tone output from the speaker 58 and the sound generated along with the vibration output by the microphone 59 and measures the sound pressure D2 of the collected sound ( Step S105). Here, the sound generated along with the vibration output includes vibration sound (operation sound) of an actuator (not shown) in the vibrator 57, for example, the mobile phone 1 is placed on the surface of a desk or the like. In some cases, it includes noises (such as chattering sounds and humming sounds) generated by the mobile phone itself as the vibrator 57 is driven.

  The CPU 101 obtains a difference between the sound pressure D2 measured in step S105 and the sound pressure D1 measured in step S103, and compares the difference with a preset threshold value D (step S106). Furthermore, in step S106, CPU 101 advances the process to step S108 when the difference is equal to or smaller than threshold value D (in the case of NO determination in step S106).

  On the other hand, when the difference is larger than threshold value D (in the case of YES at step S106), a situation in which unnecessary noise (billing noise) is generated due to vibration output by vibrator 57 is expected. . Therefore, the CPU 101 changes the drive voltage of the vibrator 57 to a value smaller than the set value up to the present by a predetermined value (step S107). As a result, the drive state (for example, the rotational speed) of an actuator (not shown) in the vibrator 57 is attenuated (decreased), and as a result, the sound accompanying the vibration output is reduced. The method for attenuating the operating state of the vibrator 57 is not limited to the change of the drive voltage, and any method may be used.

  After the setting value is changed in step S107, the CPU 101 returns the process to step S105 to measure again the sound pressure D2 after the driving state is attenuated. Then, the CPU 101 repeats the series of processing from step S105 to step S107 until it can be determined in step S106 that the difference between the sound pressure D2 and the sound pressure D1 is equal to or less than the threshold value D. Thereby, the vibration output by vibrator 57 is attenuated stepwise until it is detected in step S106 that the difference is equal to or less than threshold value D.

  If it is determined in step S106 that the difference is equal to or smaller than the threshold value D, it is determined that the ringing tone output from the speaker 58 and the vibration output from the vibrator 57 are in an optimal notification state. it can. Therefore, the CPU 101 determines that the notification is to be continued with the current speaker output and vibration output, and continues the notification state until, for example, a predetermined operation by the user is detected (step S108).

<Effect of the first embodiment>
According to the first embodiment described above, a notification state (sound pressure D2) obtained by summing up the sound output from the speaker and the vibration output from the vibrator collected at step S105, and notification only of the speaker output. When the difference from the state (sound pressure D1) is larger than the predetermined threshold value D due to the vibration output from the vibrator 57, the state of the vibration output is limited (suppressed).

  Thereby, for example, when the mobile phone 1 is placed on the surface of a desk or the like and the chatter sound is generated with the drive of the vibrator 57, the state of the vibration output is suppressed. Therefore, the user can recognize the incoming call state surely and with good feeling, for example, with his favorite ringtone, without feeling uncomfortable with the chatter sound and without being surprised.

  Note that the process of repeating the series of processes from step S105 to step S107 includes a case where the drive of the vibrator 57 is finally stopped. Further, when the drive state of the vibrator 57 is attenuated, the decrease in the drive voltage may be reduced as the difference between the sound pressure D2 and the sound pressure D1 and the threshold value D decreases. Good (the same applies to other embodiments below).

  In this embodiment, the speaker output (sound pressure D1) is detected in step S103, and then the speaker output and the vibration output (sound pressure D2) are detected in step S105. However, the detection order is not limited to this, and the processing configuration may be such that the sound pressure D2 is detected first and then the sound pressure D1 is detected (the same applies to other embodiments below). ). However, in the case of the processing configuration in which only the speaker output is executed first as in the present embodiment, it is expected that the user can recognize the incoming call only by the speaker output before starting the vibration output. In this case, since the execution time of the vibration output by the vibrator 57 can be minimized, it is preferable from the viewpoint of avoiding the occurrence of the chatter noise and the like.

[Second Embodiment]
Next, a second embodiment based on the mobile phone 1 according to the first embodiment described above will be described.

  Also in the present embodiment, the hardware configuration of the mobile phone 1 is the same as that in FIG. 1, and the content of the incoming call notification process is different from that in the first embodiment. In the following description, characteristic portions according to the present embodiment will be mainly described, and a duplicate description of the same configuration as that of the first embodiment will be omitted.

  FIG. 3 is a flowchart showing an incoming call notification process performed by the mobile phone in the second embodiment. This flowchart represents a processing procedure of a software program executed by the CPU 101 in order to notify the user of an incoming call to the mobile phone 1 in this embodiment.

  As shown in FIG. 3, the CPU 101 also performs processing similar to that in steps S102 to S108 (FIG. 1) after detecting incoming calls (step S201) as in step S101 (FIG. 1) in this embodiment. Steps S204 to S210 are executed. However, unlike the first embodiment, this embodiment is characterized in that the threshold value D is reset (updated) every time an incoming call occurs.

  That is, the CPU 101 detects the sound pressure D0 around the own terminal via the microphone 59 in response to detecting the incoming call to the mobile phone 1 in step S201 (step S202). The sound pressure D0 represents the state of the sound field where the mobile phone 1 is placed immediately before the incoming call operation starts. Then, the CPU 101 sets the sound pressure D0 detected in step S202 as a threshold value D serving as a comparison reference (step S203).

<Effects of Second Embodiment>
In the second embodiment described above, the state of the sound field around the own device (sound pressure D0) detected in step S202 is set as the threshold value D. Thereby, in this embodiment, for example, in an environment where the surrounding sound field is noisy before the start of the incoming call operation by the mobile phone 1, the degree of attenuation of the vibration output by the vibrator 57 is restricted to be smaller than that of the first embodiment. be able to. On the other hand, in an environment where the surrounding sound field is extremely quiet, the attenuation of the vibration output can be greatly restricted as compared with the first embodiment. Therefore, according to this embodiment having such a processing configuration, in addition to the effect according to the first embodiment, the user can be made to recognize the incoming state in a more appropriate notification mode.

[Third embodiment]
Next, a third embodiment based on the mobile phone 1 according to the first embodiment described above will be described.

  Also in the present embodiment, the hardware configuration of the mobile phone 1 is the same as that in FIG. 1, and the contents of the incoming call notification process are different from those in the third embodiment. In the following description, characteristic portions according to the present embodiment will be mainly described, and a duplicate description of the same configuration as that of the first embodiment will be omitted.

  FIG. 4 is a flowchart showing an incoming call notification process performed by the mobile phone in the third embodiment. This flowchart represents a processing procedure of a software program executed by the CPU 101 in order to notify the user of an incoming call to the mobile phone 1 in this embodiment.

  As shown in FIG. 4, in this embodiment, the CPU 101 also performs step S102 to step S106 and step S108 (FIG. 1) after detecting the incoming call (step S301) as in step S101 (FIG. 1). Steps S302 to S306 and step S308 having similar processing contents are executed. However, in the present embodiment, unlike the first embodiment, when it is determined in step S306 that the difference between the sound pressure D2 and the sound pressure D1 is larger than the threshold value D, the following processing is performed. Has characteristics.

  That is, if the determination is YES in step S306, the CPU 101 increases the output level of the ringtone output from the speaker 58 (step S307) and stops the vibration output by the vibrator 57 (step S308). Thereafter, the CPU 101 returns the process to step S302.

<Effect of the third embodiment>
In the third embodiment described above, when the difference between the sound pressure D2 and the sound pressure D1 is greater than the threshold value D, the level of the speaker output increases in step S307, while the vibrator in step S309. The vibration output by 57 is stopped. That is, in this embodiment, the increase in the difficulty in recognizing the incoming call of the user due to the stop of the vibration output is complemented (compensated) by increasing the level of the speaker output. Therefore, according to this embodiment having such a processing configuration, in addition to the effect according to the first embodiment, the user can be made to recognize the incoming state in a more appropriate notification mode.

[Fourth embodiment]
Next, a fourth embodiment based on the mobile phone 1 according to the second and third embodiments described above will be described.

  Also in the present embodiment, the hardware configuration of the mobile phone 1 is the same as that in FIG. 1, and the contents of the incoming call notification process are different from those in the second and third embodiments. In the following description, characteristic portions according to the present embodiment will be mainly described, and overlapping description of the same configurations as those of the second and third embodiments described above will be omitted.

  FIG. 5 is a flowchart showing an incoming call notification process performed by the mobile phone in the fourth embodiment. This flowchart represents a processing procedure of a software program executed by the CPU 101 in order to notify the user of an incoming call to the mobile phone 1 in this embodiment.

  As shown in FIG. 5, in this embodiment as well, in the present embodiment, the CPU 101 performs incoming call detection similar to step S201 (FIG. 3) (step S401) and then steps S202 to S208, as in the second embodiment. In addition, Steps S402 to S408 and Step S410 having the same processing contents as Step S210 (FIG. 3) are executed. However, in this embodiment, as in the third embodiment, when it is determined in step S408 that the difference between the sound pressure D2 and the sound pressure D1 is larger than the threshold value D, the following processing is performed. Has characteristics.

  That is, if YES is determined in step S408, the CPU 101 increases the output level of the ringtone output from the speaker 58 (step S409) and stops the vibration output by the vibrator 57 (step S411). Thereafter, the CPU 101 returns the process to step S404.

<Effect of the fourth embodiment>
In the fourth embodiment described above, as in the second embodiment, the state of the sound field around the device (sound pressure D0) detected in step S402 is set as the threshold value D. If the difference between the sound pressure D2 and the sound pressure D1 is larger than the threshold value D, the speaker output level is increased in step S409 as in the third embodiment, while the process proceeds to step S411. Stop vibration output. As a result, in this embodiment, in addition to the same effects as those of the third embodiment, the threshold value D serving as a determination criterion in step S408 is appropriately set according to the surrounding sound field, as in the second embodiment. it can. Therefore, according to the present embodiment having such a processing configuration, in addition to the effect according to the third embodiment, an increase in the difficulty in recognizing the user's incoming call due to the stop of the vibration output by the vibrator 57 is reduced. It can be supplemented (compensated) by increasing the level. Therefore, the incoming state can be recognized by the user in a more appropriate notification mode.

  As described above, in any of the above-described embodiments, it is premised on an operation mode in which a ringtone output from the speaker 58 and a vibration output from the vibrator 57 are executed when an incoming call is made to the mobile phone 1. In the operation mode, the mobile phone 1 automatically stops the operation of the vibrator 57 or the speaker when the situation (sound field) around the terminal is assumed to be noisy due to the drive of the vibrator 57. Attenuate to an appropriate level in relation to the output.

  Therefore, according to the mobile phone 1 according to each of the embodiments described above, in the operation mode in which the output of the ringtone and the vibration output are used together, it is possible to accurately adjust the incoming call notification mode according to the surrounding situation. Therefore, it is possible to make the user recognize the incoming call reliably and in a good manner.

  More specifically, for example, when the user has set a favorite melody or the like as a ringtone, the surrounding situation (sound pressure D2) collected by the microphone 59 is inappropriate due to the vibration operation. There is a case where the level becomes as large as expected to include a noise (such as a chatter sound). In this case, the mobile phone 1 automatically limits (ie, stops and attenuates) the vibration output. For this reason, for the user, the melody, which is a ringtone, is output with a higher emphasis compared to the vibration output. Therefore, it is possible to prevent an unpleasant situation that it is difficult to hear a ringtone such as a set melody (sound is muddy, etc.), so that the incoming state can be surely recognized while satisfying the sensitivity of individual users. This is preferable.

  Further, when the user carries the mobile phone 1 set in the operation mode in a pocket of clothes or in a handbag, the vibration output by the vibrator 57 is performed in the original operation mode without stopping or attenuating. Is called. Therefore, in this case, the user can recognize the incoming call by the vibration output from the vibrator 57 even in a situation where it is difficult to hear the incoming call sound from the speaker output.

  That is, according to the mobile phone 1 according to each of the above embodiments, when the operation mode in which the ringtone output and the vibration output are used together is set, even if the use environment changes as described above, the vibration output Are automatically adjusted to the appropriate mode of operation. In the case of a conventional general mobile phone, there is a problem that the setting of the operation mode must be changed one by one. On the other hand, the mobile phone 1 is excellent in convenience because it does not give the user the trouble of changing the setting of the operation mode each time.

  Furthermore, according to the mobile phone 1 according to each of the above embodiments, the vibration output is stopped or appropriately attenuated as described above, so that a secondary problem such as the mobile phone 1 dropping from the furniture surface due to the vibration. Occurrence of this can be avoided, which is preferable.

  The present invention described by taking the above-described embodiments as an example can realize the functions of the flowchart (at least one of FIGS. 2, 3, and 4) referenced in the description for the mobile phone 1 described above. After the computer program is supplied, the computer program is read out and executed by the CPU 101 of the apparatus. Further, the computer program supplied into the apparatus may be stored in a readable / writable storage device such as the nonvolatile memory 60 or the like.

  In the above case, the computer program is supplied to the mobile phone 1 by using a suitable jig in the manufacturing stage before shipment or the maintenance stage after shipment. A general procedure can be adopted at present, such as a method of downloading from the outside via a communication line such as the Internet. In such a case, the present invention is constituted by the code of the computer program or a storage medium.

  In each of the above-described embodiments, the case where the present invention is applied to a mobile phone that is a representative mobile terminal has been described. However, the present invention is not limited to the application to a mobile phone, and can be applied to a mobile terminal such as a PDA (personal digital assistant) or a wristwatch as long as it has a microphone. Furthermore, the predetermined state notified to the user by the mobile terminal according to the present invention is applicable not only to an incoming state such as a telephone call or an e-mail, but also to various state notifications such as a notification of a schedule or time. .
